Improvement in watbit-wheels

fatina stata To attachant it may cimcera."` i `Be it jknown "that VI,AOLIvnn .MBoLn-iuenn, of Yoik, inthe county of VYork and State ofPennsylvania, have invented certai `iie'w'vand useful ImprovementsinlVater-Wheels;I a d`I do `hereby declare the following to he afull,clean-andfexact description. of the san1e,referencebeing had tov theaccompanying 4drawings makingparltfof-this specification, in whiche-Figure lrrepresents, inperspective, the penstock for- `containing thewaterwheel, or `in which the 1 wheel is placed.` i y `Figure2represents, on an enlargedscale,`a vertical sectionlthroughthepenstockwaterewheel, `and gates.V Figure 3 represents` a horizontalsection through tliepenstock, and withporftions ofv the wheel brokenaway to show parts underneath them.- ,i i j Figure4 `represents a viewof the under` side of the top plate, showing 'the cams `thereon formoving the gates,` e j Figure-5 represents a diagrainshowin'g thecenters from which the curves of the buckets or gates are asccrtainedor'obtai'ned. y

`Similar-letters of reference, where they occur' in the several separategures, denote like parts of the wheel and its co-operati've parts in allof the drawings.

My invention relates to'f that class `of water-wheels `wherein a" seriesof pivoted gates is used to open, i regulate, or close the inlet issues,and so regulate the amount of water to ,be `let'lonto the wheel; and lMy invention consists, first, in curving the ianges j ofthe upper andunder plates, orcroun-plate, and cyle inder, outsideot' the gates, sojasto make .the water# way at this point of greaterarea Vthan where itstrikes thebnckets, andjthns increase its force, bydirninishl ing itsvolume area where it strikes the gates.

` ft further consistsin combining with a crown-plate whose exteriorflange curves outward and upward, a deck-plate, with an outward anddownward curved `ilange, tot thatof `thc crown or top plate.

g It further consists in conibining with an upper and an under plate,and a series of pivoted gates between' them, with studs thereon.projecting through slots in said upper plate', a deck-plate furnishedwith a series of cams, by which said gates may be operated.

lo enable others skilledin the art to make and use i myinvention, I willproceed to describe the same with referenceto the drawings.

The under plate or part of the wheel consists of a cylinder, A, which isvertical, and which has projectl ing from its'upper edge aflange," whichis` first horiccntal, as at a, to a point or `line outside of the gatesB; thence said iiange curves downward, as at I, and theneeliorizontah asat c, where it is supported by the penstock C,gandthroughrwhich iiange cthe bolts that unite this under part with the crown-plate D alsoOvei'the topplate rests upon said top or crown-plate, by means of its h.otivnafa terminera, or roux, rENNsYLvANIA. l

' pass, aswell as those which holdand adjust the, spiderE, thatsup'portsthe water-wheel shaft Ffas at d.

the cylinder A, and belowits top there is an inwardly-proj ect- Ontheinside of portion a short distance,

i ing horizontal iiange, e, against the perimeter of which and the inneredge ofthe cylinder A the vertical and horizontal iianges f g of thewater-wheel F run,'leav ing anannular space, 2, between thewheelfand theunder plate,finto which the waterv finds its way, 4and aids to raise thewheel -on its step orsuppora The crown-plate D is recessed andshouldered,as seen in iig. 2, to receive the flanges upon the top H ofthe.\vater-`wheel. j

Outsidebf or beyond'these shoulders and-recesses the crownplate ishorizontal, to-'a point as farout as the gates B'move or act, or nearlyso, and thence it curves upward, as seen at h'h, and Vlugs, a', c'project beyond the curve h, to receive the bolts that unite it to theunder part or plate, and that support the spi# der, and through it thewheel itself.

The gates B, of the form and construction shown in igs. 3 and 5, arepivoted, as at n, to the top and bottom .platesof the wheel, and uponthe upper edge 'of'each gate there is a stud, m, which projects througha slot, o, in the top plate, D, there being a stud and;

slot`for each gate.

D there is a deck-plate, G, which hub j and its downwardly-curvedexterior flange-k, leaving a space or chamber between said crown anddeck-plates for a series-of eccentric -iianges or cams, r fr, which are`made on the under side of the 4deckplate G, to project and operatein,'as will be explained.

A` shaft, l, is supported in the top and bottom plates of the wheel, andextends up vertically throughV the penstock C, and has at its upper enda hand-wheel, p, or other device by which it can'be turned.4 On thisshaft there is a pinion, q, which works into a segmental rack, s,attached to the deckplate G, so that said deck-platemay be moved to openthe gates B, which is done bythe cams lr taking against the studs fm,and turning the gates on their pivots. #The gates are closed by theaction of the water against them, as vthe portions of them that arebeyond their pivots and next the vinrushing water are Ymuch longer thanAthe other portions between sa'd pivots and the wheel proper, so thatthe pressure of the water upon these longer portions constantly tends toclose the gates, while they are opened and held open by the cams r. Eachgate being independent of the one or more ofthe gates may be clogged byanything getting in and there remaining, while the others may all close,which'would not be the case if they were closed by a positive orarbitrary movement ot" the disk or deckheel G. But while these bucketsare other in closing,

'tinued m opening that individual y self-closing by the pressure of thewater upon ther longer'ends, yet by an extended ,or oonavement ot thedeck-plate they maybe closed by said deck-plate.-

It will perceived'that t anges, h f plates to 1e cul-vi o the erownanddeck-plat by a horizontal joint. partcula' ijeot of thisro'r f ed 1 iis, in con eff' 1n with the under n" i ange b, to form a Haringwater-way or inlet passage, unbroken by angular or square corners,which,l however obtuse, will break up the regular inflow ot water, and`detract from its normal force, which rounded surfaees will not do to sogreat an extent.

On the crown-plate D'ofthe wheel there s a hol low shaft or tube, t,which vextends up through the penstook and has on its upper end anadjustable bearing and oii-bc x, I, for supporting and truing the upperpart of `the wheel-shaft F.'

' The deekpieces G 'O' of the 'penstoek` are cli or sectional, so thataccess may he had through the they cover to the wheel; and for thepurpose of getting at or into the. wheel, to clean it out or otherwise`an opening may be made-through the case or 1 so as to draw ont. thepivots and stud of one of hebuckets, and thus remove said bucket, whio:es au avenue to the wheel, and any part ofthe w heel may he turnedround to this avet g -oi' the tufo' es, allows these But the more of theplates nue. The u i gs for drawing ont'the pivots, 8vo.; eau be closedby a screw, cap, or otherwise.

The holes u in the top plate of the water-wheel, as

yshown at H, are for allowing the water that leaks a point, theywouldtouch the wheel at apoir Afu, but they are out ofi atv a point, w, sothat through-the joint between the wheel and the gate or crown-plate topass out, otherwise it would be forced up through vthe tube t.

What I elainmand desire to secure byk Letters Pat- The upper and underplates, curved beyond the gates, as at b It, for the purpose ot' makinga flaring and rounded inlet furthe water, as and fo'rth'e'purposedescribed. f

Also, in combination with the crown Bange h the deck-plate and itsflange It, off the junction ofsaid plates, as andpose described. l
